Abstract

Palier à gaz à pression dynamique à feuilles, le palier comprenant un siège (1) de palier, une feuille inférieure (2), une feuille ondulée (3), une feuille supérieure (4) et une feuille de réglage (5). La feuille de réglage (5) est en outre disposée entre la feuille ondulée (3) et la feuille inférieure (2) et utilisée pour régler l'épaisseur d'un film de gaz d'entrée entre la feuille supérieure (4) et un disque de poussée. La feuille de réglage (5) est en outre disposée au-dessous de la feuille ondulée (3), afin de réduire l'épaisseur du film de gaz d'entrée ; et, plus l'épaisseur du film de gaz d'entrée est petit, plus grande est la quantité de compression du gaz entrant, plus haute est la capacité de support du palier à gaz à pression dynamique à feuilles.
